Great info thankyou. I'll try cleaning these old cantis up and putting koolstop salmon on them and see how we go!My experience of cantis is, set up well, they're practically unbeatable. Set up badly, they're useless. I have some old deore ones on my shopper/pubber and they are great, I had my lads on a rear kiddy seat and later on a Isla tagalong, and they were sufficient and I live in a hilly area.
Contrast that with I tried to install some cantis on a road,-cross bike and no matter what I did, I just couldn't get them to work effectively. In the end, as a desperate measure, I sawed off the bosses and fitted some cheap long drop dual pivots, which had the power, but poor modulation
